Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

The U-37 family of screw terminal aluminum electrolytic capacitors from United Chemi-Con are offered in capacitance ranges of from 1,5000 to 22,000 microfarads provides high ripple current and long ...

I've recently had a few capacitors go bad on a weird formfactor board (NTX) and from the looks of it it shouldn't be too difficult to replace the bulging ones. I should need three or four 560 ...

Troubleshooting single-phase refrigeration compressors requires a technician to have a proficient understanding of capacitors. The start capacitor is one of two types of capacitors that can be found ...

Fig. 1: Spurious emissions seen on the exciter RF output. One of the biggest hassles in maintaining older equipment is getting it repaired when it fails. A lot of companies don’t even want to deal ...

In the past five to ten years, there has been a big shakeout in the capacitor industry with at least 15 major manufacturers ceasing production for various reasons. Product lines have also been ...

Many single-phase compressors require a start capacitor to assist in starting the motor. These capacitors will occasionally fail, causing a compressor to fail to start. Overheating is a primary cause ...

First, let's define a capacitor: It is an electromechanical device capable of storing electrical energy (electrons). It differs from a battery, as a battery produces electrical energy as a by-product ...
